UNIVERSAL SNAP- Application filed March 9 T0 all whom it may concern.'

Be it known that I, ALEXANDER D. SCULLY, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in UniversalSnap-Fastener Buttons, of which the following is a specification.

This invention relates to buttonclasps, and the main object is toprovide a device which may be readily used as a cuff button or forautomobile side curtains, or analogous purposes, the same being designedto releasably interloclrboth members.

Another object is to provide a button clasp composed of two memberswhich are identically similar to each other, each having means thereonfor interlocking both members to each other in a releasable manner byurging both members toward each other.

These and other objects will become apparent in the description below,in which characters of reference refer to like-named parts in thedrawing.

Referring briefly to the drawing, Figure 1 is a sectional elevationalview taken substantially centrally thru a pair of interlocked cuffbuttons.

Figure 2 is a top plan view of one of the button members, showing themethod of giving resiliency to the same.

Figure 3 is a sectional elevational view similar to Figure l, taken thrua modified form of button clasp.

Figure 4 is a top plan view of one of the modied type of button members.

Referring in detail to the drawing, the numeral 10 indicates the outerkeeper flange which is separated from the vmain body iange 11 by a stem12, said stem being adapted to be inserted into the button hole of aGulf or other article. Flange 11 is annular and of relatively largediameter and has an annular cup shaped member 13 secured thereto, Whosewall 14 is curved semicircularly. The bottom of the cup member ispreferably permanently secured to said flange 11. The wall 14 of the cupis provided with a plurality of spaced apart slits 15 which render saidwall particularly resilient. A second cup member is permanently iixed inthe larger cup by securing the bottom 16 of the former to the bottom ofmember 13. The wall 17 of this cup is annular and curves divergentlyoutward, the

largest diameter being at the upper edge. The channel 18 between theinner and outer cup members has a pair of studs 19 and 2O projectingupwardly from the bottom of the larger cup member, to which they aresecured, and are surinounted by spherical. heads 21. Said studs arepreferably aligned diametrically opposite each other, the heads 21thereof projecting somewhat above the upper edges of the cup members. hesmaller cup member is also provided with a plurality of slits 22, thepurpose therefore being the same as mentioned for the larger cup. l

The modified type of clasp button shown in Figures .3 and 4 is ofsimilar design to the preferred form, but the outer cups are shapedsomewhat differently. The outer cup 23 is permanently mounted on anannular flat plate 24 which has a plurality of elongated holes 25therein, which provide means for securing the device to an article ofapparel or the like. Clips or stitches may pass thru said holes for thepurpose described. The encircling wall of the larger cup is taperedoutwardly, the upper edge 26 being curved inwardly to form a hookededge. Said outer cup is provided with a plurality of radial slits 27 forthe purpose of resiliency. A sleeve 28 is mounted within the cup, itsupper edge being divergently curved toward the hooked edge 26 of theyouter cup member. Said sleeve also has its wall slitted at variousplaces, as shown. A pair of studs 29 having knob heads 30 are connectedbya cross bar 31 and rise vertically from the channel 32 formed betweenthe outer cup and sleeve members, the bar of the studs being permanentlyfixed to the bottom of thel sleeve.

The device isy used in pairs only,that is,V

it takes two members to provide a complete clasp button. When twomembers are to be interlocked, the same are brought together, so thatthe spherical heads 2l of one member face the channel 18 of the oppositemember. Both members are then urged toward each other. As the heads beardown upon the cup members, the wall segments thereof will give way,spreading in opposite directions and permitting said heads to enter intothe channel 18 beneath the curved edges of the cup, wherein they arereleasably retained in interlocked relation. In this manner a doublelocking is accomplished as each button member carries a pair of stems,the heads of which engage the Cup edges of the opposite member. Thebutton members when interloeked may be readily separated by pulling thesame away from each other.

Another 'feature which is apparent is that my locking members provide amuch greater Wearing sur-race than those now in common use, and they"iterloeh when brought together in any position on their peripheries.thus eliminating the necessity er rotating one with respect le theother. as is necessary in many pesent types, to align the oppositeinterlocking parts.
